六年8班     11号   李日炜

I think air pollution is the most serious. Factories produce a lot of smoke and the traffic produces a lot of of fumes. 

They cause air pollution. If we keep on causing air pollution, we won′t have fresh air to breathe and we will be easy to get sick. We ought to take public transport more often. We ought not to always drive our own cars. Factories ought not to produce too much smoke.

Let′s protect our earth together. Pollution is bad for our health.
